[petyosi]

Fixes #70
Fixes #69

Pull Request Overview

This PR adds default export support to all packages in the monorepo, allowing developers to use import logfire from 'logfire' as equivalent to import * as logfire from 'logfire'. The changes include explicit construction of default export objects and some test command updates.

• Adds default export objects to index files for all packages
• Updates test commands to use vitest run instead of vitest for CI compatibility
• Fixes test expectations to match the actual behavior after changes
